T 0 all whom it may concern:

Be it known that I, l/VILLIAM SOHELBLE, a citizen of the United States, residing at 381 Box Ave, Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Machines for Making Boxes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making boxes, and with reference to its more specific features, to machines for making boxes or parts of boxes, from relatively stiff paper, such as cardboard, etc., and a covering of ornamental or finishing character.

One of the objects of the invention is the production of a practical machine for making a box or box element, which will retain its designed shape, and not readily warp.

Another object of the invention is the provision of a simple and efficient mechanism for making a box or box element from a plurality of strips or blanks, one of said strips serving as an ornamental covering and preferably embodying two or more colors.

Another object of the invention is the provision of an automatic mechanism of a relatively simple character for the production of a box or box element from continuous webs of material.

Still other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

By this machine a box or box element is automatically produced from a plurality of webs of paper, or similar material, one of said webs being composed of relatively stiff and heavy paper, such as cardboard,and the other being relatively thin and flexible, sections of the latter web being readily adapted to fold or bend and form a conforming covering for sections or blanks severed from the heavy, or body, web. The preferred shape of the box or box element formed by the machine is prismatic, preferably rectangular, similar, as to shape, to the box and elements isclosed in the patent of Carlos Holly, No. 1,158,211, patented October 26,.

1915. The present invention involves improvements over the machine disclosed in the patent above referred to, but in some particulars is similar thereto, and reference is accordingly made thereto for a fuller description of some of the devices herein mentioned. Likethe machine of the former application, the present machine involves a main frame supported on standards and pro viding a horizontal table 1, over the surface of which is intermittently fed a body web 2 coming from a suitable source of supply. The body web is preferably longitudinally scoredat difierent points orlines widthwise thereof, these lines corresponding to the lines which will become the corners'of the box or be}; element to be produced. In the present case the body portion of the boi: flange is formed by sections of the body web ('ee Fig. 31 and the grooves 3, 4, 5 and =3 are provided therein by reason of the scoring above mentioned. The scores are formed by'removing the material of the web,

. tance between the centers of grooves 3 and 4 and 5 and 6 is the same, and corresponds to one dimension ofthe box, and the distance between the centers of grooves 4 and 5 corresponds to the other dimension of the box. The body web 2 is also preferably beveled as by being scarfed, pref rably on opposite faces, as at T and 8, the scariing exposing the raw material of the body for the more ready taking of adhesive. One of the beveledv faces is preferably sized, or pro vided with adhesive, as glue, before being 'operated'upon by this machine, while the other beveled face is glued bv the machine as the web passes over the table 1, all as deposed scribed in the aforesaid patent, the gluing dauber forthis purpose being carried by cutter carriage 28, hereinafter further described.

grooved portions 3, 4, 5 and 6, and the beveled surfaces 7 and 8 are superposed, the

distance between the corners of the box.

measured along the side having the superbevoled portions will be equal to the side comprised by the central blank division 11. r

The body web, scored, scarfed and sized,

and guide fingers 13 (see Figs. 1 and 4) The dimensions of the end divi-' slons 9 and 10 of the body blank are such that when the blank is folded at thewhence it passes across the table 1 between knurled feed rollers 14 and 15 and above a straight cutting edge 16 provided at the edge of the table, a bracket 17 providing a continuing portion of the table, as at 18. The guides 13 are sector-shaped, enter the grooves of the web and restrain lateral movement thereof. The rollers 14 and 15 yieldingly grip the body web at the central division between adjacent grooves, and are suitably geared together and operatively arranged to rotate at proper intervals and for a predetermined amount, to thereby feed the body web step by step relatively to the edge 16 a distance equal to the depth of flange desired for the boX to be formed. In the present instance the movement of'the feed rollers 14 and 15 is effected by intermeshing pinions 19 and 20 driven through a pinion 21 connected tothe latter, and a gear 22, the latter in turn driven step by step by a pawl on lever arm 23 oscillated by a cam 24 through the instrumentality of a connecting rod 25 (Fig. 8). The guide fingers '13 move with the body or flange web, so that the friction between the web and said fingers need not be overcome by the feeding pull on the web, and when the web comes to rest the fingers are moved back to their original position, these movements being accomplished by an arm 250, on a cross shaft 251, to which latter the sector fingers 13 are fastened, the arm 250 being positively operated by cam 252,'through the instrumentality of bell crank lever 253 and connecting rod 254, to cause the fingers to move in a direction opposite to that of the body web, forward movement of said fingersbeing effected bv a,

spring 255 connected to rod 254 and to the frame of the machine.

The body web having beenfed so as to dispose the proper amount thereof in advance of the cutting mechanism, as before stated, it comes to rest, and a blank or sec tion is cut therefrom by a cutting disk which is moved across the'web. The cutting disk is seen at 26 (Fig' '4) and comprisesa rotatable disk mounted on an axle 27 journaled in a' carriage 28 having dovetail sliding ongagement with a substantial fixed cross piec 29 ofthe frame of the machine. This dish is moved back and orth across the web in cooperative relation with the ed means of a rod 30 suitably connected one end to the carriage 28, and at its other end to a lever 31 fulcrumed on the main frame and operated through a second rod and a crank arm 33 on a short'sha'ft the last journaled in the frame and provided with a pinion 35 having oppositely disposed locking faces 36 adapted to cooperate with teeth and a cooperative locking face of a gear 37 fast on a short shaft 38' journaled in the frame, the proportion of teeth on the respective pinion and gear being such that the disk 26 moves across the web in one di action during one rotation of shaft 38, and back during the following rotation, and is locked between its movements in opposite directions. The body web 2 is held in position to be severed by the knife 26 by clamping jaws 89 (Figs. 4:, l4 and 15) projecting from a rock shaft pivoted on the table 1, said jaws being positively pressed to hold this web against the table near the edge 16 by means of a cam d1 co'cSper-ating with a roller on rock arm as joined to shaft 40 means of rod 43 and arm id. A spring -l-5 serves to raise the jaws 39 when permitted by cam ll. A section having been severed from the body web 2, as above described, is ready to be assembled with a cover.

The numeral 46 represents a bracket at the side of the main frame below the table 1 and in general vertical alinement with the assembly point of the body and cover sections. @n this bracket are supported the roll cover web 46, and the gluing, guidng, nsioning and continuous feeding dei o the cover web. The devices for gluin the cover web may be of any citiharaeter, but preferably comprise a. ie reservoir or tank 47, on which is roably mounted a glue-applying roller 1-8, x as to dip into the glue in the tank. A supply or roll of cover web of suitable width is carried by a rotatable reel 49, and is let over guiding and tensioning bars 50, 51 in a path, thence over roller 48, thence over a scraper bar 52, which removes superfluous glue, thence around a removable guide roller 58, and thence between a pair of rollers 54 and 55, the lower one of which latter rollers is positively driven by a belt or cord 56 from a convenient continuously driven shaft of the machine, and the upper one having a knurled periphery adapted to rest upon the cover web. Roller is preferably carried by a rod 57 pivoted to a bracket 58 and is held against the web by gravity as sisted, if desired, by a spring 59. A latch 60 serves to retain the roller 55 in position. The glue-applying roller 48 is so constructed as to leave an unglued space longitudinally of the strip of coverweb. In its preferred form this roller provides two peripheral surfaces 61 and 62 (see Fig. 3e), laterally spaced so as not to contact the web centrally, and of such width, respectively, as to leave a slight margin of unglued web at the edges of the web. The roller 55 is of a width to contact the central portion of the web without coming in contact with the adjacent glued portions. From the rollers 54 and 55 the cover web passes around a guide roller 63 and thence in a depending loop to a curved uide portion 64: of a web-positionb ing device having a keeper 65. r

On the frame of the machine at one side of the path of the body web is a guideway 66 in which slides a plate 67 of which the curved guide portion 54 is a part. Supported by and overhanging the plate 6? is a bracket 68, on which latter is mounted a resilient arm 69 having a narrow finger 70, the latter being positioned so as to rest upon the unglued central portion of the cover web and clamp said web against plate 6?- with sufficient pressure to cause the web to move with the plate 67, on movement thereof in one direction, and yet this pressure will. permit the web to be drawn past plate 62 and finger 70,when the web is positively advanced. by a separate feeding device, as will hereinafter appear. The amount of pressure between the plate 57 and finger 70 may be regulated by a screw 71. Sliding motion in opposite directions is communicated to plate 67 through a rock shaft 72 having an arm 7 3 pivotally connected to plate 67, said shaft 72 being mounted in bearing brackets Te and having another arm 75 to which one end of a rod 76 is pivotally joined, the other end of said rod being pivotally connected to a rock arm 77. A roller 78 cooperates with a cam 79, properly contoured to give the requisite movements to the sliding plate 6?, as will appear further on. The plate 67 is provided with flanges S0 to accurately guide one end portion of the cover web 46.

Fixed on a depressed portion of the main frame, as at 81, beneath the plane of the path ofthe bodv web and in the general vertical plane or the cover web is a transverse bracket 82 having a recess 83 (see I igs. l and 20). Above this bracket is situated a cover web support or carrier to receive and temporarily retain that portion of the cover web which is to be cut off and assembled with the sections of the body web before described. In the preferred embodiment, this cover web support, or carrier, comprises a hollow block 84 having a flat upper surface provided with openings 85 communicating with the chamber of the block. By means of a suitable flexible tube, 86 (Figs. 6 and 16}, the chamber of the block communicates with a valve chamber 87 containing a valve having a stem 88 pro leeting outside the valve chamber, the stem having an arm 89 adapted to be operated to open and close the valve by a 90 through the instrumentality of rock lever 91, connecting rod 92, bell crank lever 93 and link 94'. Said valve controls communication between the pipe 86 and an air exhausting device, as a vacuum pump placed at a convenient place on or near the machine. The block 84, at its end adjacent the sliding plate 67, has a forwardly projecting lug 95, the upper face of which is flush with the top of the block, and the inner edge 96 of which is adapted to serve as a fixed blade to oooperate in providing a slit in the forward edge of the section of the cover web 46 (see Figs. 80 and 82).

Disposed to operate in a plane across or normal to that of the cover web sections are folding and pressing devices comprising a lower pressing jaw 97, and an upper combined folding and pressing jaw 98, the jaw 97being the upper face of a plate 99 extending crosswise the machine and the jaw 98 comprising a rearwardly projecting portion or flange of a plate 100, also extending transversely of the machine. Movement of these folding and pressing devices across the plane of the web is accomplished by rods 101 fixed to the plate 99at their upper ends,

and pivoted to bell crank levers 102 having rollers 108 in the path of cams 104. The plate 100 is supported on rods 101 by means of depending stems 105 fixed at one of their ends to the plate 100 and extending through openings in brackets 106 fastened to rods 101. The stems 105 are providedv with adjustable shoulders 107, and between said shoulders and the brackets 106 are springs 108. Brackets 109 are fixed to the plate 100, and supporting stems 110. depending fromv the hollow' block 84 pass loosely through slots in the horizontal arms of brackets 109 and through openings in the bracket 82. Nuts 111 provide adjustable shoulders on stems 110, and springs 112 are interposed between shoulders 111 and the brackets 109. Below brackets 109 the stems 110 have stops provided by nuts 118. The folding devices not only move across the path of the web sections, but also longitudinally thereof inorder to complete the fold of a portion of one section around the edge of the other,as will be explained further on, and in order to accomplish this longitudinal movement, a rock shaft 114 is dis posed in the recess 88in the bracket 82, and has arms 115 which bear against the inner face of plate 99 and have a cam action at proper times to press the folding devices forwardly and permit them to mo've rearwardly, on which latter movement portions of the web sections will come between the jaw 97 and the jaw 98. Motion is given the rock shaft 114 at proper times and for proper amounts by a rod 116 through the instrumentality of a cam 117, the cam operating to positively move the folding devices forwardly, and springs 118 serving to move them in the opposite direction. The

stops 111 are designed to contact the under face of bracket 82to determine theextreme upper position of the block 84. After the folding of one section around another, the

upper jaw 98 is moved toward the lower jaw to effect a squeezing of the fold between these jaws, this movement of the upper jaw being accomplished by cams 119 cooperating with one arm of rock levers 120, the other prising a. plate 129 pivoted to member 127 arm of said levers being pivotally connected to the upper jaw by rods 121, springs 122 being employed to keep the levers 120 in contact with the cams 119. A spring 124 performs a similar. function for bell crank 102.

In order to feed the cover web onto the upper surface of the hollow block 84 preparatory to severing a section therefrom a reciprocatory feeder comprising gripper jaws is provided (see Figs. 4 and 17). A dovetail groove 125 is provided in an inclined inner face of the bracket 82, this groove providing a horizontal guideway transverse of the machine, in which slides a carriagehaving the gripper jaws mounted thereon. This carriage may comprise a plate 126 conforming to the transverse shape of said guideway and an upwardly extending. arm 127 fastened to plate 126, the upper endof said arm being disposed to move in a plane directly over the block 84 and providinga lower gripper aw 128. On the member 127 is an upper gripper aw comat 180, a flat spring 181 being disposed to press the upper jaw toward the lower jaw. The upper jaw preferably has a longitudinal series of teeth 182 depending from the central. portion thereof, the foremost tooth curving 'into the upper face of the upper gripper, as at 188. 'The numeral 184 indicates a connecting rod, one end of which is pivotally joined to plate 127, the other end being pivoted to rock lever 185, in turn connected by rod 186 to a crank arm 187 on a short shaft 188, which latter carries a pinion 189 having a series of teeth interrupted by a locking face. Pinion 189 meshes with two alternate series of teeth 105. 140 and 141 and locking faces 142 and 148 on shaft 88, and the number, proportion and V arrangement of the teeth and lockingface of the pinion 189, and the cooperative teeth and locking faces on shaft 88- are such that the gripper carriage is advanced to bring its grippers adjacent the end of the cover web at one sideof the machine,'rests a short while, andthen returnsto its original position on the oposite side of the machine, where it again rests before again advancing to feed-the cover web.

In the operation of the machine the gripper jaws 128 and 129 move from one sideof the machine toward the other and come to rest with the jaws 128 and 129 disposed, respectively, above and below the end of the cover strip 46. These jaws are in open position while advancing to grasp the cover' strip and as the gripper carriage comes to rest the aws are closed by a pawl lever 144 pivoted on the am 127 and having a high portion 145 and a low portion 146 forming a cam surface on one arm of lever 144. The other arm 147 of thispawl lever is disposed per carriage comes to rest the pawl will contact the pin 14:8, and continued advance will cause the pawl to turn in a direction 15 to bring the low portion of the cam surface iave closed upon the cover strip i6. opposite diiection will pull the cover strip across the blocl 842, and at this time the valve lereinbefore mentioned will cut off on from the chamber of the block. ion the carriage arrives at the opposite of the machine, the pawl 1 1 1 will be turned by the dog 1&9 to open the jaws 128,

. 129 when a sutficient amount of the cover web has been pulled or fed, and then the carriage will move farther to remove the grinner jaws from the end of this web. The the; remains at rest while ip is sever d, assembled with a sec on, and removed from block'84e, eupon the advance to repeat the 1g operation just described. Just the gripper jaws release the cover web the suction takes effect on the web by the opening of the valve referred to and the web will be held on the block 84 by sucion. 21 roper length is th n severed from web, and a slit is formed in the front eds; of the section as will now appear.

On the front face of the cross piece 29 is adjustably fired a bracket 150 comprising a ont portion 151. Mounted to reciprocate in this bracket as a guideway is l rod having affixed at one side ting below its lower end a g blade and at the other f a ii similarly projecting a slit- 21s the rod 152 descends the A tee with the outer edge 155 of the block 84 and lug 95, to sever the cover web, and the blade 15% cooperates with the 0 JG of "aid lug to slit the web at its front really simultaneously. In order to ase the severing and slitting at the proper oints the cutting edges of the blades 153 and are in line with the inner faces of guides 156, spaced apart just the width of he lug do. in this manner the cover web h" ovement of the carriage in the The more important function of these memthe severin and slittin takin lace n 1 b folded independently. In order to effect the reciprocatory movement of the severing and slitting lades, a rock lever 157, fulcrumed on a standard 158, is connected by a link 159 to one arm of a lever 160, the opposite arm of which is joined by a rod 161 to a rock arm 162, and has a roller 163 cooperating with a rotary disk 161 having a concentric peripheral surface interrupted by a cam or de pressed portion 165, into which the roller 163 descends and thereby permits the m0- mentary descent of the scoring and slitting blades 153 and 154, under the influence of the spring 166, these blades being positively raised as said roller moves out of thecam portion 165. The rod 152 has a rearwardly extending arm 167, against the lower face of which the lever 157 plays, and in a recess 168 in said face. One end of spring 166 is attached to rod 152 and the other, end to bracket 150.

The respective severed sections of the body web and the cover web are to be assembled, folded into a flange, and associated with a head to form a complete box, al-

though it will be apparent that, viewed in some aspects, the invention contemplates the formation of a flat. assembled composite blank, or a folded element which may serve as a collar for a box. In the present embodiment the echanism for assembling a body section with a cover section comprises "a transfer device which pneumatically grips the severed body section and advances it to be adliesively assembled Wlilll the cover section. Numerals 169, 169 represent two hollow members extending transversely of the machine, the lower faces of these members each being plentifully perforated to communicate with the inner chamber at a plurality of points. Thus, when the air is partially or wholly exhausted from the inner chambers of the members 169, the lower faces thereof operate as pneumatic grippers.

here is to control the position of the section of the body web after it has been severed by the knife 26, and to dispose this. section in proper position relative to the cover section. In the present embodlmentthe body section, after having been severed, is advanced in a horizontal plane to such a position above the cover section lying on block 8-1, that the rise of said block, as before described, will cause these sections to be superposed, the body section on the adhesive face of the cover section, and in such relative position as to place the front edge of the body section parallel to the front edge of the cover section on a line distant from the front edge of the cover section corresponding approximately to the distance of the inner end of the slit in the cover web from said edge. Also in the present embodiment, the rear or trailing edge of the cover section will be inrear of the simi- V piers 169 will place the assembled sections in the path of the mechanism which assembles heads with said sections and folds and secures the sections thereto, thus forming boxes.

7 To accomplish the foregoing functions, .and others appurtenant, the transferring grippers 169, 169 are each supported by hollowarms 170, 170 from a hollow head 171. The chambers of the members 169, 169 communicate with the interior of the head 171 through the arms 170, 170, and the air may be exhausted from said head through a valve in a valve chamber 172, a flexible pipe 173 connecting the head and the chamber 17 2, the valve in the latter being controlled by a stem through the instrumentality of a cam 174, and operative connections similar to the control of the valve in chamber 87. Thus at proper times the air pump or vacuum device may be connected or disconnected from the grippers 169, 169. The head 171 is supported by parallel rods 17% slidably guided in pairs of brackets 17 5 and 176' on the top of cross piece 29. Numeral 177 indicates a transverse rock shaft connected to rods 174, 171 by links 178, 17 8, and motionis given to the rock shaft to advance and retract the grippers 169, 169 by means of an arm 179 on shaft 177, joined by connecting rod 180 to an arm 181 of a bell crank lever, the other arm of this lever having a roller 182 cooperating with a cam 183, the latter suitablycontoured to give the requisite movements to grippers 169, 169. The

.cam 183 positively moves the grippers 169,

169 forwardly, their rearward movements being effected by a spring 1841, which latter is preferably connected to a fixed pin or hook on the shaft 177 and to head 171, so as to take up any slack in the operative connections intermediate the head 171 and the cam 183.

The machine is set in motion by means of a belt pulley 185 which may be continuously driven from any suitable motive source, and which is adapted to be connected and disconnected from a main drivingshaft 186 by any suitable form of clutch 187, {indicated diagrammatically only) the latter adapted to be thrown into and out of position to couple and uncouple the pulley 185 to the shaft 186 by means of a lever 188 and a shift-rod 189 having a handle 190. On the main driving-shaft is' a small gear 191 meshing with a larger gear 192 on a horizontalcountershaft 193 journaled on the main frame at the lower rear portion thereof, and by means of bevel gears 194: and 195 motion is communicated to a longitudinal shaft 196 which drives thebelt 56 for the purpose of giving continuous rotary motion to one of the cover web supplying rollers 51. The countershaft 193 is also provided at an intermediate portion with a bevel gear 197 engaging a similar gear 198 on a shaft 38, which latter operates to drive the body web cutter and the cover web feeding gripper jaws, as hereinbefore described. Also on the shaft 193 are mounted many of the cams which operate to give the special motions to the different parts of the machine, as hereinbefore set forth.

After the body and cover web sections have been adhesively assembled and interfolded as before described, the composite blank so'formed will be advanced by the grippers 169, 169 into the path of a series of formers or mandrels 199, these formers moving in an endless path and being supported at the ends of arms 200 projecting from a rotatable hub 201. The mandrels are driven intermittently and at their positions of rest one of them will be in position to receive or will have received a box'head from a head magazine 202, said head being fed to the mandrels 199 as explained in the patent hereinbefore referred to. Referring to Fig. 1, the mandrel 199 at the left-hand side in its position of rest will have received the central division of the composite blank hereinbefore referred to, the endsof the blank projecting laterally at each side of the man drel, the pneumatic grippers supporting said composite blank adjacent or against the mandrel. Before these pneumatic grippers are deenergiz-ed or release the composite blank, a jaw 203 moves into position to clamp said blank against the mandrel. The pneumatic grippers then release the blank and further operations on the blank are ac complished by the former and its associated folding devices, which fold the blank transversely around the side of the mandrel and also around a box head which has been previously delivered to the front face 'ofthe mandrel and is held thereon by suction. After the composite blank has been released by the pneumatic grippers, and clamped to .the mandrel 199, adjacent the edge of the the sake of clearness. The hub 201 is driven through the instrum ntality of a mutilated gear which is driven from shaft 193, by a chain 205, and other operative connections preferably as set forth in said prior application.

The box flange produced by the machine herein described preferably exhibits different colors exteriorly, one of the colors appearing a narrow strip of color around the flange adjacent the head of the box as indicated at 206, the cover web being colored appropriately to provide this strip at the place referreu to. The cover web may be colored in any approved manner to provide the diiierent colors on the flange of the box, andin the present embodiment two colors are employed transversely of the cover web, the one appearing at 206 (see Fig. and the other appearing at 207, the line of intersection of the colors being a line longitudinal of the web and at an intermediate trans verse portion thereof. A simple way of producing the multi-colored web is by overlapping webs of the desired colors and gluing them together at the overlapped portions. The resultant web is mounted upon the reel 49 for delivery to the machine.

Furthermore, both the body web and the cover web are fed to the machine so that the severed sections thereof when in superposed assembled relation, as shown for instance in 31, will have the grain of the cover ction arran ed across or at an angle to 1e grain of the body section, as shown in ig. 31, wherein the broken lines 208 reprent he grain or" the cover section and the broken lines 209 the grain of the body sec- T he cover web accordingly resists retching to a greater degree longitudinally when assembled into a box the plain fiat surface so desirable in a prismatic box, and that the walls of the box do not curve or warp out of shape to the extent observed in boxes of diilerent construction.

The operation of the machine should be obvious from the foregoing description, but a brief summary thereof will be given. A narrow web d6 preferably of a width sufficient to cover the length of the body section and extend beyond both the forward and rear edges of the body section, is supported upon the reel 49, is passed between the guiding and tension rollers 50 and 51, thence into contact with a glue-applying roller 48. thence around a guide bar and between rollers and 56 whence it depends in a loop, its end being passed into the keeper and into position to be yieldingly gripped between the finger and the plate 6?. It will be understood that the grain. of the web etfi extends longitudinally of said veb. A body web 2 of such a .weight and relative han transversely, and it is found that the flange so resulting substantially preserves stillness as to form a substantial body section is grooved, beveled, and one edge sized, as hereinbefore described, and the end of such a web is led to the machine at an angle to the direction of feed of the cover web, passing between the fingers 18 and yielding presser rollers 210 and between said and the guiding plate 12 onto the table 1, its end being also passed between the feed rollers 14 and 15 into position to be operated upon by the cutter 26. t will be understood that the grain of this web extends longitudinally of the web. The machine may now be turned over once or twice, whereupon the cutter 26 will operate to provide a straight front edge for the body web.

Continuous operation of the machine may then be started by operating the clutch 187. The plate 67 will be advanced to project the end of the cover web transversely of the machine in the vertical plane of the block 8-1, the carriage 127 will pass across the machine and theend of the cover web will be received between the grippers 128 and 129 and gripped thereby, the teeth 132 taking hold of the cover Web at the portion free of the glue or other adhesive. During these operations the cutter 26 will pass across the machine in one direction and sever a body section from the web 2 in rear of the advancing end of said web. The carriage 127 will then move in the reverse direction across the machine and pull or feed the cover web onto the block or pneumatic gripper 8a, and when a length of cover strip suiiicient to cover a flange of a box peripherally, and overlap. has been fed, the grippers are re leased by the pawl 149, but just before the cover web is so released, suction becomes effective in the chamber of the block 8. to energize this gripper, so that when tl e cover web is free from the grippers it will be held on the block 84 by the suction. The carriage 127 rests momentarily while the cover section is assembled with the body section and removed from the block 84 toward the de-' vice designed to further operate thereon. While the cover section is being positioned as just described, a body section will have been cut off from the web 2, and as soon as this section is severed it will be automatically gripped to the grippers 169 on account of the reduced pressure therein at that time. The grippers 169 then move forwardly in a right line and into position above the cover section held on the bloclrS-l, as shown in Fig. 21, the front and rear edges of the body section being positioned within the front and rear edges of the cover section. The block 8e then rlses, and the sections referred to are superposed one upon the other,

a plurality of colors of the cover section intercepting' the length of the body section, the adhesive or glue being therebetween, as shown in Fig. 22. Thereupon the folding and pressing jaws 97 and 98 rise and fold the longitudinal edge of the cover section across the transverse edge of the body section, as illustrated in Fig. 23, and thereafter said jaws move rearwardly so as to fold the edge of the cover section into position above the body section, as illustrated in Fig. 24;. The jaw 97 then remains at rest while the jaw 98 moves down, and the interfolded elements are squeezed so as to become firmly secured together as illustrated in Fig. 25. Thereupon the jaws 9'? and 98 are released from their squeezing position and moved forwardly beyond the edge of the assembled sections and thereafter moved downwardly into their original position, as illustrated in Figs. 26 and 27. During the several operations above mentioned, the grippers 169 retain their hold upon the body section. 'After the jaws 97 and 98 have returned to position below the plane of the assembled sections, the grippers 169 move forwardly and place the composite blank thus produced in the path of one of the formers 199, the two grippers 169 passing one on either side of the path of the former and supporting the composite blank so that the advancing wall of the former moves into position against or closely adjacent that division of the composite section corresponding to the division 11 of the body section. The grippers retain the blank in this position until the jaw 203 shall have been moved to clamp the composite section against the former, whereupon the suction is cut off from the grippers 169 which then return to position closely adjacent the body web to receive another section out off from the end of the body web. Before the body section and the cover section are assembled as described, and after the cover section has been disposed upon the table 84, the severing knife 153 and "the slitting knife 154: descend, the one severing acover section from the end of the cover web in rear of the advancing end of said cover web, and the other simultaneously slitting the cover section transversely there of, providing the slit 21 shown in Fig. 30. In said figure the dimension of the slit is exaggerated for the sake of clearness, it being understood that the slitter 154: is sharp and makes a clean out having no substantial width at this point. r

The composite blank gripped between one face of the former 199 and the jaw 203 will extend laterally at either side of said former. T he former then moves past a folding horn 212, which partially folds the extended portions ofthe composite blank toward the lateral walls of the former, said folding being completed by folding jaws 213 disposed at a lower position of rest of said former. The assembly of the composite blank with the head need not herein further described, as themechanism for a'ccom plishing the assembling is preferably the same as that disclosed in the prior applications before mentioned. Thus by the above described apparatus are accomplished, among others, the objects hereinbeifore referred to.
